LTC2631HTS8-LM10#TRMPBF

Overview

The LTC2631HTS8-LM10#TRMPBF is a single 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc., housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 2.5V and operates on a single supply voltage ranging from 2.7V to 5.5V. The device utilizes a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical characteristics include a maximum Integral Nonlinearity (INL) error of ±1 LSB, a typical settling time of 3.8µs at 3V, and low power consumption of 180µA at 3V. It incorporates a power-on reset circuit configured to initialize the output to mid-scale upon power-up.

Feature Summary

• Integrated 10ppm/°C precision reference providing a 2.5V full-scale output
• I²C serial interface compatible with standard and fast modes up to 400kHz
• Power-on reset option to initialize DAC output to mid-scale
• Guaranteed monotonic operation over the operating temperature range

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive applications
• Optical networking devices

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the H-grade designation aligns with the required automotive temperature range of –40°C to 125°C for the target application environment. Ensure the LM10 suffix correctly specifies the 10-bit resolution and mid-scale power-on reset behavior as documented in the manufacturer's selection guide.

Selection Notes

Select this component when a 10-bit resolution with ±1 LSB INL accuracy is required in a compact TSOT-23 form factor. The H-grade temperature rating (-40°C to 125°C) is necessary for automotive or harsh industrial environments. Choose the LM10 variant specifically if the system requires the DAC output to initialize to mid-scale rather than zero-scale during power-up sequences.

Part Context

This part belongs to the LTC2631 family of single-channel voltage-output DACs. The family offers variations in resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and temperature grades (C, I, or H). The HTS8-LM10 designation specifically identifies the high-temperature grade, thin SOT-23 package, 10-bit resolution, and mid-scale reset configuration within this product line.

Replacement Considerations

Direct pin-compatible substitutes within the same family include LTC2631ITS8-LM10#TRMPBF for industrial temperature range (-40°C to 85°C) or LTC2631CTS8-LM10#TRMPBF for commercial range (0°C to 70°C). Verify that the replacement part meets the specific -40°C to 125°C operating requirement if the H-grade is critical for the design.
